Let P(alpha,0)" and "Q(0,beta) be two-points on x-axis and y-axis respectively. Tangents from P touch the hyperbola (x^2)/(a^2)-(y^2)/(b^2)=1 at M_1(x_1,y_1)" and "M_2(x_2,y_2), similarly tangent from Q to this hyperbola touches it at M_3(x_3,y_3)" and "M_4(x_4,y_4), then (given alpha,beta ne 0 )

Answer»

`x_1=x_2" and "y_1+y_2=0`
`x_1+x_2=0,y_1=y_2`
`x_1+x_4=0,y_3=y_4`
`x_3+x_4,y_3+y_4=0`
